Description
The Microchip Technology Inc. MCP6401/1R/1U family
of operational amplifiers (op amps) has low quiescent
current (45 µA, typical) and rail-to-rail input and output
operation. This family is unity gain stable and has a
gain bandwidth product of 1 MHz (typical). These
devices operate with a single supply voltage as low as
1.8V. These features make the family of op amps well
suited for single-supply, battery-powered applications.
The MCP6401/1R/1U family is designed with
Microchip’s advanced CMOS process and offered in
single packages. All devices are available in the
extended temperature range, with a power supply
range of 1.8V to 6.0V.
